When driving on a wet road, how much should you reduce your speed?

When driving on a wet road, it is essential to reduce your speed to maintain control of your vehicle and reduce the risk of hydroplaning. Reducing your speed by about one-third is recommended because it helps to improve traction and allows for a greater reaction time to sudden stops or changes in traffic conditions. Wet roads can significantly decrease the friction between your tires and the roadway, leading to longer stopping distances.

Driving slower also allows you to better navigate potential hazards such as puddles, which can cause your vehicle to skid or slide. By adjusting your speed appropriately, you are better equipped to handle the dynamics of a wet driving surface, thereby enhancing your safety and that of others on the road.
